What plant pigments are found in plants other than the green pigments?
Carotene - an orange pigmentXanthophyll - a yellow pigmentPhaeophytin a[1] - a gray-brown pigmentPhaeophytin b[1] - a yellow-brown pigmentThese are some of the other pigments found in plants other than green pigments.
What molecules other than chlorophyll absorb and reflect certain colors?
Chlorophyll a has absorption maxima of 430nm and 662nm. Which corresponds to violet and red. Chlorophyll b has absorption maxima of 453nm and 642nm. Which corresponds to blue and red. Hope that helps
How do plants with foliage that is not green in color photosynthesize?
Plants with foliage that is not green in color can still photosynthesize because they contain pigments other than chlorophyll, such as anthocyanins or carotenoids, which can also capture sunlight and convert it into energy. These pigments may have different absorption spectra than chlorophyll but can still be used in the photosynthesis process.
Why are some plants red or purple when all plants have chloroplasts and that is what makes plants green?
Plants can appear red or purple due to the presence of pigments other than chlorophyll, such as anthocyanins. These pigments absorb different wavelengths of light, giving the plant its distinct color. Additionally, the expression of certain genes can cause the production of these pigments, resulting in plants that are red or purple in color.
What stores food or contains pigment in cells?
Food is stored in specialized organelles called vacuoles in plant cells, while pigments are stored in plastids such as chloroplasts and chromoplasts. Vacuoles store nutrients and waste, while plastids contain pigments such as chlorophyll (green pigment in chloroplasts) or carotenoids (orange and yellow pigments in chromoplasts).
Why algae contain pigments other than chlorophyll?

What other pigments are used to trap energy?
In addition to chlorophyll, other pigments such as carotenoids and phycobilins are used to trap energy in plants and algae. Carotenoids absorb light in different wavelengths than chlorophyll, while phycobilins are found in some algae and cyanobacteria to help capture light energy for photosynthesis.
Why do plants also contain accessory pigments?
Additional pigment in plants, other than chlorophyll, enable these to utilize maximum solar radiations. For example carotene and xanthophylls absorb those radiations which remain inaccessible to chlorophyll a & b.

Why are leaves green except in the fall?
Chlorophyll gives plants their green colour. There are other pigments in the leaves too, such as xanthophylls (yellows) and carotenoids (yellows, oranges and reds). These pigments are also used in photosynthesis but occur in lesser quantities than the green chlorophyll. The combinations of the different pigments make different shades of green. Now the reason that plants look green is that they are trying to obtain energy from the sun using a particular part of the light spectrum, mainly the red and infra red wavelengths. If you remember from your physics classes the colour you see is the colour that is reflected from the object, the other colours are absorbed. So in the case of green plants, the green wavelength is reflected and all the other colours, especially reds and blues, are absorbed to drive the energy cycle in the plants. Chlorophyll does best in the red (around 670 nm) and blue (around 500 nm) areas of the spectrum. That's why many plants have the additional pigments (xanthophylls and carotenoids) called accessory pigments that feed light energy to chlorophyll "a" from light. Chlorophyll is almost useless in the green part of the spectrum, and doesn't absorb that colour. That is why most plants are green.

What function do photosynthetic pigments other than chlorophyll serve?
Photosynthetic pigments other than chlorophyll mostly participate in the energy-transfer processes just as chlorophyll. They can also function to protect the photosynthetic reaction center from auto-oxidation. In non-photosynthesizing organisms they have been linked to oxidation-preventing mechanisms.They can also serve as free radical scavengers.
What role do plant pigments play in the process of photosynthesis?
Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change.
What are accesory pigments?
Accessory pigments are molecules found in photosynthetic organisms like plants and algae that help to capture light energy and pass it to chlorophyll, the primary pigment involved in photosynthesis. These pigments broaden the range of light wavelengths that can be absorbed and enhance the efficiency of photosynthesis by supplementing chlorophyll's light-harvesting abilities. Common examples of accessory pigments include carotenoids and phycobilins.
